Log in and Log out for mobile app

Can we have the function to log in and log out from the mobile app? It works fine on the website portal, the mobile app should have it too.

Right now, there is the link Facebook and Scopely ID to account on the mobile app, but once you linked it, the options are still there, and there are times where incidents happened when people got unlinked from their game account and cannot get back in, needing to contact support and lose days of activity.

Let us actually logs out from the mobile app, either by choice from the settings, or something else.
